pool filter sand is great. Like all sand though, it can mess up your filter. Mine kept on getting messed up because my jurupari swim around the tank with sand in their mouths, spitting it everywhere. Sometimes some gets in the intake and i have to clean out the impeller well. The ray will definitely love the sand, but might kick some up into the intake as well. One imporant thing about sand! It allows less room for BB, and by removing so much gravel, you might kick your tank into a mini nitrogen cycle. Careful with ammonia spikes, especially with the ray. Other than that, do it! Good luck!
